add 24-hour format option to use Time hook for clarity

[amir-rahmanii]

Description:

This PR explicitly adds the 24-hour format option to the useTime hook. Previously, the 24-hour format was the default but was not explicitly mentioned. This change improves clarity by making the format option clear in the code.

Changes:

• Added explicit support for the 24-hour format option in the useTime hook.
• Updated documentation to reflect the default format and the available options.

Why this change:

This change helps improve code readability and clarity, ensuring that the default format is explicitly defined as 24-hour while still supporting the 12-hour format option.
